device, but here shown in the position after having received the plateand then canted over. Fig. 9 is a similar view, but showing the'plato aslifted through the guide L; and Fig. 10 is sectional plan ofthecoating-pot.

Similar letters refer to like parts in all the figures.

According to our invention we place rollers or guides near the top ofthe pot containing 5 the coating material, between which the plates tobe coated are to he passed. Yihen these guides consist of rol ers, theyrecruited in bearings, and are driven by gearing in opposite orreversedirections to one another.

A is the potcontaining the coating material. B the entrance box orhopper for containing the fiuxing material, and C the exit or finishinggrease box hopper.

In carrying our invention into practical effeet we have found fixedguides znu'ch superior to revolved guide-rollers, as the latter appearto counteract to a certain extent the preparatory action of the flux onthe entering' nncoatcd plates, and have other disadvantages.

D are the guides, which are or may be immersed in the coating materialcontained in the pot A, and may he carried up to the top oi the entrancellux box or hopper B; or, instead of thus continuing them up, we mayemploy rollers at the upper part of the said fluxbox B, for the purposeof guiding and assisting the plate down throughthe aforesaid lower fixedguides, D, and into the molten metal. Two hoppers, I; and 0, areprovided in the case here shown, or one divided hopper may he used. Thefirst hopper-via, the entrance flnx-hox l'3contains the llux,eonsistingol tat lowand palnroil, or other materialsuitable for limitingor preparing the plate to take the coatinc; of metal or alloy, such asthat ln.-.reinal'ter The second hopper or finishinge box, G, containsthe material used for preventing the surl'aceof the metal from oxid- 9oizing and for finishing; the plate. This material may be tallow, as isnew usually'einployed holes in the frame IL for the rods (l to pass forsuch purpose. lhe uncoated plates, having been prepared in the usualmanner by pickling, are introduced one after the other into the firsthopper, B, contaiuingthe preparatory flux. At the bottom of the hopperthe plate is passed through or along the fixed guides D, or, rather,along that part of the guides which is immersed in the molten metal. Asstated already, this may, though not so shown here, be assisted byguide-rollers provided in the upper part of the hopper B. The plate isthen nipped by a gripping appliance or tongs, H J K, below the fixedguides D D. The plate is then caught by one end of a weighted lever, andit is canted or pushed over to the under side of the nip of the rollersE, whereby the plate is carried up between same and through the secondhopper, 0, containing the tallow or finishing-grease or other equivalentmaterial, whereby the metal is prevented lrom oxidizing and thethickness of the coating on the plates is regulated. The surface thereofis also reduced and consequently improved. N hen the plate reaches thetop of the rollers E, it is removed from the machine by the attendant.

\Ve will now more particularly describe the construction of the clip orgrippingtongs H J K and other interior parts of the apparatus.

G G are four rods fired on a horizontal spindle, G, which latter canrock in bearings placed at the bottom. of the tinning-pot A. On thespindle G is also fixed a lever, i provided atits upper end with ahandle, 1 and a weight, F, for causing a partial revolution of thespindle G and the consequent canting over of the rodsG. Thetwo middlerods,G.serveasguides for the gripping-tongs H J K, which can be raisedand lowered thereon, as required, its weight being more or lesscounterbalanced by the molten metal or alloy. The rod J, for actuatingthe grippinglinger K, is formed at its upper end as a handle, J, for theworkman to. grasp in his hands. The hook-shaped gripping-linger ispivoted at K to the lower end of the rod J, and said gripping-linger isforked and jointed at K to two lugs on the frame ii. The two lugs areprolonged upward, uniting in a rod, ii, the upper end of which is formedas a handle, Ii, for the workman to grasp in his hand together with theaforesaid handle j. The rods Jand it are kept close together by a metalloop on the upper end of rod J. The

through are made as .llOlh', so as to allow for a certain amount of playin the Working and canting ol' the nipping appliance. "the frame H isalso provided with horns ii, for preventing theplate from leaving itwhile canting.

By reference to Fig. 10 it will be seen that the lower part of the potA. is somewhat rounded at itsends and provided with ribs for the purposeof reducing" the frictional surface against which the plntimay rub whenpassing up to the guide L. This lulu-r is uri ranged in the lower partof tin: finishing-l grease box C, and made box shape or with l closedends. The two ends or horns ll' ol' the frame H workin the two spacesA), formed in the pot A for the purpose, and the hook or finger K,whenreleased orthrown baek,works in the center groove, A. It will b noticedthat the lower part of the pot A is made of such a form as'to contain aslitt le molten metal as possible. The right-hand side of the pot is alsofor this purpose formed wider in one part-that is to say, with a recessat A for the rods J and H to drop back into, (instead of making the potof the same width all along.) The entranee-homier ll is at its lowerrighthand side formed with a recess, as shown at B, Fig. i), in dottedlines, for the purpose of giving room for the rods H and J to be raisedhigher up than shown in case of coating plates of less depth.

E E and E E are rolls arranged in the finishiuggreasc box 0, and servingto reduce and finish the coating on the plate.

"We do not eontine on rselvcs to the position of the nippers shown here.

The operation is as follows: The workman takes hold of the; rod or leverH bythe handle it and raises it, together with the parts J and K,against a stop, M, Figs. 8 and ii, so farthat the hook or nippingdingerK does not quite reach the surface of the molten metal. llc then placesthe plate N to be coated into the hopper B, containing the ilnx,,('which quickly prepares the plate to receive the coating.) through theguide I), and past the guide I) and into the nip of the tongsthat is tosay, between the linger K and the rod lb-and by raising the handle. jagainst the handle ll, bringing them together in his hand, he therebycauses the bottom part of the plate to be nipped between the hook orlinger ii and tinrod li. lie then pushes down the whole appliance, withthe plate, along the two middle guiderods, G, untilthetopcdgeofthcplnli- X (all according to its depthor size is lJt'lU'itthe bottom edge of the hoppers l3 and U, and he then lets the handle jgo down, whereby the plate is released from the grip of the linger K.Another workman or boyihvn, bynieuns 01' the weighted handle I", cuntsthe guiderods ti over to the left, when they will mn-npy the positionshown in lfig. and keeps tin-in in that position. Thelirstworltinunthenlills the nipping appliance by the handle it, and so brings the plat cup through the box-guide ii, and causes it to lnentered lwtu'vtiillwl'iWt'l' pair of rolls, l'l l'l--11aniely, into the position shown inlrig. ti. The boy then pushes back or lets go the lever P, which, by thecounterbalanee ol'the weight, then falls back into its originalposition, together with the guide-rods (i and the nipping appliance,which then lifted a-little highertail according to ihrdvpih of tlnpla el\' i into a position ready to receive a fresh plat The rolls 1-] carrythe linisln-d plate to the next pair or pairs, 1'1, wh ch de liver 1 heplate out of the machine. While the plate with the nipping appliance isbeing lifted the back or right hand ol the frame it (see Fig. 2) slidesup along the guide-rods G, receding to the right as it descends.

It will be seen from the drawings that the form and arrangement of theguides D and D in the entrancehopper B, the nippers G HK J, and theguide L in the finishing-grease box '0 are such that in case a plateshould be put on wr0ng-that is to say, on theright-hand side, Fig. 2, orback of the guide-rods Gwhile the latter are in a forward or verticalposition-then the workman has only to throw the rods G back into thenormal position, (shown in Fit. 2,) and the plate can then be taken outby raising the top handle, h, and removing the plate by means of tongsinserted between the entrance-hopper B and th neck or right-hand side ofthe pot A.

The above mode of operation applies to the manufacture of tin plates;but when making terne plates the workman retains the nip of the finger Kagainst the plate N until the latter has been canted over into theposition shown in Fig. 8, because the great specific gravity of theterne metal would otherwise float the plate up to thesurface before ithad been properly coated and before it had been placed in the rightposition to enter the box-guide L. The weight of the gripping-tongs H JK may, especially for tinning, be balanced by a balance-weight and chainconnected toziiever and rodsu ch, for instance, as by the arrangementshown in dotted lines in Fig. 2. The horns ll" hold the plate inposition until it is nipped with thefinger K. The cantingmovement of therods G G may, if desired, be effected automatically bysuitablelevcr-connections to the tongs H J K, so that by the movement of thelatter they (the rods) are canted and brought back. As the parts G, H,and K, which are the only parts that come in convtact with the plate,never entcrthe uppermost layer or surface of the molten metal, and,also, as the parts of the rods H and J, which do work through thesurface of the molten metal, are placed outside the entrance-hopper I 3,any scrutl' or other impurities that may be on the surface of the moltenmetal cannot be carried down and made to adhere to the plate. v

We do not confine ourselves to the position of the nipping applianceshown in the drawings, or to the number of the rollers. The above modeof proceeding, then, consists in passing the plates down through thepreparatory grease box between guides in and through the coatingmaterial, and when coated up and between the pressing-rollers andthrough the finishing-grease contained in the second hopper, and outfrom the samc'in a finished coated condition, and all in one pot, and,soto say, by one operation and with only a small quantity of coating metalin the pot, and by'ihe employment of a nipping appliance which nevercomes to the surface of the coating metal,and whereby the plate isbrought into the nip of the pressing-rollers in the exit orfinishing-grease box.

In conncctionwith this invention we use in the shallow .extrancehopper Ba flux of spirits of salts, prepared in a peculiar manner to bedescribed and claimed in a separate ap plication.

Having now described the nature of our said invention and in what mannerthe same is to be performed, we declare that we are aware that it hasheretofore been proposed to prepare and to coat metal plates in onebpenat-ion and in a vertical pot, and sometimes with rollers on the exitsidein the coating metal and in the flux, the plate having then to befinished in another apparatus-videlicet, a finishing-grease pot. We arealso aware that it has been pro posed to prepare and coat and finishmetal plates in one operation, and in a pot in which the plate is madeto travel in a more or less curvilineardirection from one end of the potto the other by rollers, chains, or other means. \Vc do not claim alitter for raising the plate, as this has been used with entrance anddelivery rollers. Neither do we claim a finger to move the platelaterally; nor a cradle to raise the plate up between delivery-rollers.in our improvement the plate is simply guided as it passes down into thecoating metal, and it is nipped, ,and after, immersion is raised throughthe finishing, metal and between the pairs of finishingrollers.

We claiml. The combination, in an apparatus for coating and finishing aplate in one operation, of a vertical pot for the molteircoating metal,an entrance-hopper. thcrci n containing preparatory flux. and stationaryguides for the plates to be coated, a nipping appliance and cradle whichreceives the plate to be coated from the said guides, and which isadapted to nip and to lower the plate and hold it while being coated andto raise and releascthc plate, and operating handles and stops whichprevent the nipping part from rising out of the coating metal, andv abox on the exit side of the coating-pot, which box contains finishingmaterial and the finishing-rollers, and a bore guide which leads thecoated plate into the nip of-the finishing-rollersand keeps the risingand iloatingscrnll'from the plate, substanlially as set forth.
